Referring to accompanying drawing the present invention is described clearly.In Fig. 1, multiple layer metal foil construction 10 is positioned near the wall 12 of wanting insulating vessel as shown in figure, as near the inner surface of stove exterior wall.Surge layer in the structure sheaf is denoted as C, and separation layer is denoted as S, and skin is denoted as E.It can be such that characteristic of each layer and physics require.Surge layer C has produced required height and the spacing of special-purpose through ripple forming, as 0.25 inch high/dark and 0.75 inch spacing (between the summit).Can use traditional ripple forming device and can go out any ideal form by ripple forming, as sine curve, horn shape etc.Each metal forming can be by belling, form figure or carry out moulding or processing by other modes, subsequently its through ripple forming so that be assembled into structure of the present invention with separation layer.In addition, an independent surge layer C of the present invention itself can comprise by ripple forming or independent ripple forming and a plurality of metal foil layers of suit together subsequently.U.S. Pat 5939212 has been described such multilayer corrugated paillon foil, and it can be used as surge layer C of the present invention.Surge layer C can be by Zhang Yiqi belling or several carried out ripple forming and subsequently separately the back by the single sheet layer of belling separately and/or corrugated sheets layer so that as the layer C of structure of the present invention.
Separation layer S of the present invention as shown in Figure 1 can be the plane, belling or band figure line or that be prepared from by alternate manner or textured.Separation layer S also can be made into corrugated, and condition is that ripple has certain angle or locatees by other modes, thereby separation layer S does not have alignment surge layer C, makes on the separated position of surge layer C and still stay.Itself can comprise multilayer metal foil separation layer S, if these layers have played the effect of isolating the separation layer S of surge layer C.Separation layer S can be carried out ripple forming by Zhang Yiqi belling or several and be separated subsequently the back separately the single foil layer of belling and/or corrugated foil lamella so that as the layer S of structure of the present invention.
Outer E can be the plane, belling or band figure line or be suitable between outer E and wall spare 12, producing air gap by alternate manner, multiple layer metal foil construction wherein of the present invention is added on the described wall spare.When outer E preferably contacts wall or when surface, multiple layer metal foil construction of the present invention can be by on the surface or wall that surge layer C are abutted in the parts that maybe will shield of will insulating.
In a preferred version of the present invention, the arbitrary layer of multiple layer metal foil construction of the present invention or all layers can be by bellings or by alternate manner band lines or the figure line is arranged.Separation layer S and outer E can be produced air gap by belling or help adjacent layer or structure between air gap.Surge layer C carries out ripple forming subsequently preferably by belling.We find amazedly, and belling not by flattening-out, but still keeps all or nearly all belling structure in whole ripple process when ripple forming.
In this manual, term " belling ", " projection " are to comprise traditional mode and the relief that forms lines, figure or other form in thin slice or slice plane.Such projection in one deck of structure of the present invention has produced or has helped between adjacent layer and layer or use between the surface of this insulation system and produced air gap.
The shape of projection is preferably in each belling summit and produces point.These points can be circular slightly or can be cusps.Raised points is producing minimum contact so that the heat transfer between inhibition layer and the layer between the layer.Used belling instrument or roller preferably produce sharp keen projection, and wherein raised points penetrates thin slice and is in raised points and produced little opening in the lamella.The girth of these openings is made of the vertical edges of breaking through or penetrate thin slice.These vertical edges around opening on raised points or summit have produced belling lamella point contact adjacent layer equably, and this more likes the contact of blade type, and this has further suppressed in such convexity layer and the heat transfer between the adjacent layer.
Obviously, in above-mentioned structure of the present invention, surge layer C can be just the same or different aspect bellows-shaped or other characteristic.Similarly, separation layer S can be just the same or different aspect characteristic.The direction of ripple or angle can be change and those skilled in the art can regulate the direction of ripple or angle so that produce desired result according to foregoing.These layers can be accepted to seal and produce the air bag of sealing or can openend produce air or gas flows through its location, chute ground, so that dispel the heat in whole liner or panel scope or dispel the heat from the liner that comprises multiple layer metal foil construction of the present invention or panel.
A special benefits of structure of the present invention produces by composite wave lamina C and separation layer S, described separation layer can be along any direction relative positioning surge layer C to each other, and need not consider surge layer C each other alignment and lost layer with layer between desirable gap.Separation layer S of the present invention keeps separating of surge layer C and interval.Particularly advantageous characteristics of structure of the present invention are that the wave groove that surge layer C constitutes is positioned parallel all.The groove of surge layer C has constituted the passage that air or other gas can circulate or circulate with smooth separation layer S, thereby heat is flowed or diffusion by described structure.If there is not separation layer S in such structure, then surge layer C can overlap merging and can lose spacing and formed conduit between layer.
